COUPLING.

SPECIFICATION forming part of Letters Patent No. 744,505, dated November 17', 19023.k n l Application filed October Z7. 1902. Serial No. 128,919. (No model.)

T @ZZ whom, it may-concern:

Be it known that I, ROBERT M. DIXoN,a citizen of the United States, residing 'at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Couplers, of which the following is a specication.

' My invention relates to couplers, and more particularly to Whatis known as the straightport type of couplers, although the inven tion is generally applicable to couplers.

In the accompanying drawings I have shown one member of a coupling in which my invention is illustrated.

In the drawings, Figure I is a broken-away sectional view through a coupler member, hereinafter for brevity termed a coupler; and Fig. II isa face view ,of the bushing, the said bushing having a non-circular form, herein shown as rectangular. Fig. III is an end view of the coupler.

In the drawings, a indicates the couplerhead, preferably provided with suitable lugs or locking means b c. The coupler is shownV as of the straight-port type. lThe headis apertured and provided with a rib or shoulder e. The face of the recess in the coupler-head is beveled, as atf, for the reception of the gasket structure. The gasket g is preferably a composition gasket or a ber gasket and is molded on a collar h, having thereon a rib il. Suitably secured to the collar h are springs j, having the hooked ends k, which are adapted to engage in the rear of the rib or shoulder e in the coupler-head.

As shown in the drawings,'the recess in the coupler is not of circular form. In the present instance it is substantially'square, the

corners being rounded. For obvious reasons the gasket which its within the recess is similarin shape thereto, as is likewise the frame or collar h.

The principal advantage of employing a gasket of the form shown is that the area for the passage of steam is increased and a long bearing-surface obtained at the top of the gasket-that is to say, when the two members of the coupling are coupled together with thergaskets in contact and aresuspended by the iiexible hose in the usual manner the point of application of the compression strain is at the top of the gaskets.

In Fig. II, I have shown aline wx, which indicates this long bearing-surface. vHaving described my invention, what I claim, and desire to secure by Letters Patent, 1s

I. The combination of a coupler-head and a gasket having an extended bearing-surface t for receiving compression strains.

2. In a coupling, the combination of a coupler-head having a substantially rectangular orifice and a gasket of substantially rectangular form having a tapered face and seated in the said orifice.
